NEST'ING-MACHINE.

Specification of Letters Patent.

Patented Dec. 2, 1919.

I To all whom it may concern:

Be it known that I, HAROLD C. HARVEY,

a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Nesting-Machine's; and I do hereby declare that the following is a full, clear, and exact de scription thereof.

The present invention relates to new and useful improvements in machines for nesting cup-shaped articles whereby they may assume a most compact relation for storage or shipping, a particular application of the machine being the nesting of bon bon or the like cups, stamped from a single sheet of paper.

It is primarily the object of the present invention to provide a simple machlne whereby this nesting operation may be carried out in a most ready manner and wherein the placing of the cups'by an operator for the nesting operation is facilitated so that an operator not necessarily skilled in the use of the machine can readilyfeed cups thereto for a desired rapid operation of the machine.

Paper cups of the hon bontype, stampe from a single sheet of paper, usually assume a nearly cylindrical shape as they are discharged from the forming dies, and it Is a further object of the invention to provide means for spreading the cups to insure their movement into nesting relation prior to nesting'engagement of the cup by the machine.

A further object resides in the provision of a machine of this character which is adjustable for reception of cups of'various the accompanying drawing in which Figure l is a side elevational view of a nesting machine embodying the present lnvention.

Fig. 2 is a horizontal sectional View through the machine on the line 2-2 of Fig. 1.. i

Fig. 3 is a vertical sectional view on the plane indicated by the line 3-3 of Fig. 1 through the nesting throat and adjacent port ons of the machine.

Fig. 4 is a detail sectional view on the line H of Fig.- 1 showing the spreading mechanism in plan.

Fig. 5 is a perspective view of one of the cups for the nesting operation on which the present embodiment of the invention is particularly adapted.

Fig. 6 is a detail sectional view on the plane of Fig. 3, showing the means for adjusting the machine for different sizes of cups.

Referring now more particularly to the accompanying drawings, the machine includes a main frame comprising the base 10 having a standard 11 rising' from its rear and having a standard 12 rising from its front portion and supporting a horizontal bar 13, the ends of which support the ends of an arch 14: from which rises a standard section 15 connected at its upper end with the upper portion of the standard 11 by a top transverse sill 16. An intermediate transverse sill 17 connects the top of the arch with the intermediate portion of the standard and the lower transverse sill 18 connects the lower portion of the standard 11 with the horizontal bar 13, this sill being cut away for the reception of a throat block 19 provided with a pair of throat passages 20 extending vertically therethrough and in radial alinement with a shaft 21 journaled in a bearing arm 22 projecting forwardly from the standard 12. The upper end of the shaft carries a head plate 23 on which is secured to a turn table 24 provided with a series of radial pairs of cup seating openings 25 adapted to successively aline with the throats 20. This turn table is movable over a stationary table 26 secured on the sill 18 and horizontal bar 13 and provided with a central opening receiving the head plate 23 and further provided with a pair of openings 27 receiving upstanding annular flanges on the throat block 19 surrounding the throats 20 whereby an uninterrupted throat passage is afforded from the seating openings 25 of the turn table. Thus, upon rotation of the turn table, pairs of cups may be successively carried into alinement with the throatsfor movement therethrough, and while I have shown a pair of nesting throats,it is obvious I that but 'a single throat or any number of throats may be employed, in conjunction with a corresponding arrangement of seat ing openings.

' t For receiving and conveying nested cups from the throats, a pair of chutes are provided in the form of a double chute-way, ex-

' tendingdownwardly from the .throats and then laterally of the machine. This double chute way comprises-a central guide strip 28, common ;to the sides of both chute passages,

' a pair of bottom strips 29 and a pair of outer guide strips 30, these strips being connected together at their upper ends and at spaced portions along their stretches by transverse bars 31, each secured atits central portion to the center strip 28 and then bent rearwardly and bent outwardly therefrom for securement to the outer sides of the strips 29 and then bentinwardly for securement to the outer sides of the strips 30, each of these transverse strips thus forming a pair of connected U-shaped portions. The connect ng member at the upper ends of the chute str ps is provided with an outwardly extending lug 32 and this lug is engageable by a screw tion of throat blocks and channel ways of different sizes to adapt the machine for operation on different sizes of cups.

For moving the cups through the nesting throats a shaft 35 is journaled in the upper end of the standard 11 and in a bearing 36 on the sill 13, and this shaft carries on its inner end a crank wheel 37 from which extends astub shaft 38 connected by pitmen 39 with a pair of plunger shafts 40 slidable in the sills 16 and 17 and carrying plunger heads 41 on their lower ends adapted to move through the seating openings of the turn table and through the plunger throats for nesting cups carried over the throats by the turn table. The shaft 35' is driven through the medium of a set of reducing gears 42 connecting it with a shaft 43 carrylng a belt wheel 44, and the outer end of the shaft 35 carries a balance wheel 45.

For rotating the turn table in successive steps, synchronized with the operation of the lungers, a vertical shaft 46 is journaled in t e frame sills and base and is driven from the shaft 35 through the medium of itermeshing bevel gears 47 This shaft carries a gear wheel 48 meshing with a gear wheel 49 mounted-on a shaft 50 carried by a bearing arm 51 projecting laterally from the sill 1S, Mounted on the shaft 50 is a crank wheel 52 to which is pivoted one end of the pitman 53 having its other end pivoted to arock arm 54 which is mounted on the turn table shaft 21. A pawl 55 has one end pivotedtothe rock arm and is engageable with a series of ratchet teeth 56 cut into the periphery of the turn table, this pawl beingnormally urged toward the turn table by a retractilespring 57 secured thereto and to the rockarm. The outer end of the rock arm issupported on a guide arm 58 projecting from the frame bar 13. Thus upon continuous rotation of the shaft 46,

the pitman will be oscillated to procure successive rotative steps of the turn table through the medium of the pawl 55. The

turn table is held a ainst excessive rotative movement under in uence of the pawl by a leaf spring 59 secured toone end of the arch l4 and bearing against the periphery of said turn table.

To effect a spreading of the cups prior to the r movement over the throats 20,' whereby their proper nesting engagement is assured upon depression through the throats, a bar 60 is secured on the lower portions ofthe, plunger shafts 40 and adjustably carries a pair of arms 61, having depending spreader heads 62 of inverted conical shape at-theirfree ends, the connection of these arms 60 to the bar being effectedby clamping bolts 6 passed through the ends of the bar an through longitudinal slots 64 in the ends of the arms. These spreader heads are en. gageable 1n cups seated in the turn table;

openings 25 immediately succeeding .the

cups in nesting alinement with the throats 20, and a spreading operation is obviously carried out slmultaneously with the nesting operation. The slotted connections ofthe arm 61 permit their adjustment for seats of various sizes in the turn table.

As shown in Fig. 6, the sizes of the seats of the turn table may be varied by inserting bushings 65 having various internal diam- 1 eters, in the seating openings 25 of the turn table, and this-adaption for different sizes of cups is earned out in conjunction with the securement of a throat block 19 and chute ways adaptedfor a corresponding size of cup. Thus the machine may be readily adapted wlthin reasonable limits for various sizes of cups.

the entire area of the turn table is available for the placing of cups in the seats thereof, and that no interruption to the operation of the machine occurs should any number of empty seat openings pass under the plunger heads.

While I have described the movable cup carrying table of the machine as a turn table, it is obvious that any table member movable in regular steps under the plunger heads may be employed, and that various changes of structure, to meet differing conditions of use, may be employed in any manner, without departing from the spirit of my invention.
